Diamonds are a Space Elevator's Best Friend?

Over at the Space Review Sam Dinkin ask's whether a space elevator worth its weight in diamonds?

"Diamonds have a big advantage over carbon nanotubes. They are currently being produced in commercial quantities. Chemical vapor deposition (CVD) is being used to flood the jewelry market with extremely high quality diamonds at 10-30 percent below wholesale prices of natural diamonds. Substrates as wide as 15 centimeters have been reported as a base for diamond growth. That’s hundreds of times the area that’s needed for a space elevator cable."

Your thoughts?
